Lossless output, free, no upload required
Convert WebP images to PNG entirely in your browser. Lossless output with full transparency preserved. No uploads. Works with any WebP file including those with transparent backgrounds.
Lossless output
Pixel-perfect quality
No uploads
Files stay on your device
Transparency kept
Full alpha channel
PNG is lossless. The output is pixel-perfect with full transparency preserved. PNG files will typically be larger than the original WebP.

All processing stays in your browser. Nothing is uploaded.
WebP is a modern format with excellent compression, but not every application supports it. Older desktop software, certain print workflows, some email clients and submission portals still expect PNG or JPEG. If you have received a WebP file and cannot open or use it where you need to, converting to PNG solves the problem immediately.
Editing in Photoshop or older software
Some older versions of design tools do not support WebP. PNG is universally accepted.
Submitting to portals that require PNG
Government forms, document upload systems and academic platforms often restrict accepted formats.
Sharing in email or messaging
Some email clients and messaging apps do not render WebP images inline. PNG displays everywhere.
Preserving transparency for design work
PNG is the standard lossless transparent format for design files, icons and graphics.
WebP achieves smaller file sizes than PNG through more efficient lossy or lossless compression. The same image stored as WebP at 80KB will typically be 150 to 300KB as a PNG. This is expected and does not indicate a problem with the conversion.
PNG trades file size for universal compatibility and lossless quality. The output PNG contains every pixel exactly as decoded from the WebP, with no further compression loss. If you later need to reduce the PNG file size, the image compressor can apply OxiPNG lossless optimisation to reduce the PNG file size without changing any pixels.
Compress your PNG with OxiPNG
Reduce PNG file size with lossless OxiPNG optimisation. No pixel changes.
Convert PNG to JPG
Need an even smaller file and transparency is not required? Convert to JPEG.
Convert PNG back to WebP
Going the other direction? PNG to WebP reduces file size by up to 26%.
Combine images into a PDF
Merge your PNG files into a single PDF document for submissions.
WebP is not universally supported in older software, desktop apps, and some email clients. If you need to open a WebP image in Photoshop, share it in an environment that does not support WebP, or submit it to a system that only accepts PNG or JPEG, converting to PNG gives you maximum compatibility. PNG is supported by every image viewer, browser and application.
No. The conversion is lossless. WebP is decoded to raw pixel data and then encoded to PNG, which is itself a lossless format. Every pixel in the output PNG is identical to the corresponding pixel in the original WebP. No compression artefacts are introduced.
Yes. Both WebP and PNG support a full alpha channel for transparency. The conversion preserves transparent areas exactly, including semi-transparent pixels. This makes WebP to PNG conversion safe for logos, icons and graphics where precise transparency is required.
This is expected. WebP achieves smaller file sizes than PNG through more efficient compression. The same image that is 80KB as a WebP will typically be 150 to 300KB as a PNG. This is the trade-off for lossless quality and universal compatibility. If file size is a concern, PNG to WebP is the direction that saves space, not the reverse.
No. All conversion happens entirely in your browser using WebAssembly. Your WebP files never leave your device. You can verify this by disconnecting from the internet after the page loads, conversion still works.
Yes. Drop multiple WebP files at once or select them from the file picker. Each file converts independently. Download them individually or as a ZIP file.
All modern browsers (Chrome, Firefox, Safari, Edge) can open WebP files directly. On Windows, you can open WebP files in the Photos app on Windows 11, or install the WebP Image Extensions from the Microsoft Store for Windows 10. On Mac, Preview supports WebP natively. For older software that does not support WebP, this converter is the fastest solution.
PNG to WebP
The reverse. Convert PNG to WebP for up to 26% smaller files with transparency.
JPG to WebP
Convert JPEG to WebP for 25 to 34% smaller files.
PNG to JPG
Convert PNG to JPEG when transparency is not needed and maximum compatibility matters.
